while cranking though, it drop to about 11.5 volts . I presume thats normal?

Pull the hi-tension lead out of the distributor cap and hold near ground (with a small gap).
With ignition On, crank the engine pulley past the TDC mark by hand or starter. You should get some kind of spark, although if you turn slowly the spark may be weak. (again look out for the lead - insulate yourself)
Check the distributor cap inside for signs of cracks or carbon arc tracks.
Also, check to see that the little carbon contact for the center terminal is in place; without that you can have spark but it won't get to any plug wires!

Im no expert, but if you are unsure about cranking, and other issues, (not permenantly ofcourse but a way of trial and error) run a wire direct from battery or other 12v source to coil ecu and anything else that requires it but are unsure about when cranking. if it starts you know you are not getting power to an item when cranking. (you may have already tried it but it is how i solved my wiring probs with my 2t (i know it is simpler but intermittant dead shorts in your loom are almost impossible to detect otherwise)
good luck with it mate, Jamie
I just checked my coil setup in the TA22 (1972 - may be different colours)
I dont have EFI but i do have the EFI electronic distributor
hopefully it helps - basically the other wires to the computer should be checked with the efi wiring diagram
[EDIT: 1 wire runs from the negative coil terminal to the ECU - IG terminal i think]

this is how I had it wired up is was this ok . also whats the BR from ta22 loom

oops, ignore my comment, seems that you have got that issue covered.
keep at it mate, let us all know what happens in the end for future reference.
(ill be doing a similiar thing in my ta22 with my 3tgte)
Good luck mate - Jamie
Hey dude,Originally Posted by Neverland
I know what you mean i had the same feeling when i had fuel problems with it. Im really sorry but i dont think i can be of much help, on my car i deal with everything except electrics, it helps having an electrical eng. for a dad
. Though unfortunatly he cant be of any help because he is at the coast for the next 2.5 weeks, i will try and get an email to him but i dunno how well it will work as he has limmited internet access

I suspect this is why you only got power to the coil when on ACCOriginally Posted by Neverland
From looking at my TA27 and some wiring diagrams it looks to go to the + terminal on the coil. The black/red wire runs from the ignition switch.

As the wiring diagrams and my TA27 are wired
("to coil" - should read "to distributor)

this was the case with my 2tc, (except i had a dead short) but mine would start, and then die in the ass, 1 second later. this could be a result of the carby and not efi. but this issue would explain a lot. maybe something to consider.
Thanks agin to all you guys+rep coming your way
had a stroke of luck today, Invid (Oh mighty one) came round and we went over the wiring again.
Found out a few interesting thing :?
1:- the dizzy actually has an internal ignitorrare and a gooden
2:= the injector resistor wasn't earthing at all. it seemed to be positive connected![]()
we followed it to BO wire which was funnyly enough a pos. hehe
3:- while cranking we lost compression to cyl 2 3 ... WTF we thought cranking couldn't have shat a piston skirt. After a few minutes of bambosaled looks we though we might have jammed a valve open, so we took off the cam cover, cranked her again and watched in
ABSOLUTE AWEas the exhaust cam rolled over and the intake cam sat motionless...........(we're phucked i thought)
On closer inspection the guide pin that locks the cam gear to the cam had, and I mean MAGICALLY dissapeared, was not there, or... had fallen into the sump.(the latter being the most possible).
after a quick debate Seb and I finally agreed that the pin was more than likely sitting in the sump and it was best, actually we couldn't be motivated, to remove anything to get it out so it was left there . Easy fix a 8mm drill bit shortened to 1.8mm should do the trick !
Presto Magnifoco, guide "drillbit" pin tightly in aligning the cam retighten big fat 19mm bolt to cam. No cam/cam gear moveys disaster averted
(I know I should get it out but...ce la vie) lol
Tmrw I'll try to keep the mistress idlingfor more that 3 seconds
stardate suplimental, captains log 0000001 " finally 1 to me *YES*..... 4 frigging long 8 hour days, 30deg + heat to celica"...![]()

YAY !!!!! we finally have success![]()

What I found is that the wires going to the negative coil , were loose because I hadn't tightend if enough.
now all thats left is to tidy up the wiring and test again.
new exhaust gasket and bolts. oxy sensor gasket(this will have to be homemade )
then down to the exhaust shop for extrator back exhaust.
then tune.
on a side note. has anyone noticed a split second delay in accelerator depression to the engine actually accelerating?

Well guys, i'm still having problems idling. To keep it running I have hold the throttle open, I'd say 1/2 way. Then its still really lumpy.
I've tried moving the dizzy round while trying to maintain 1000rpm, but it doesn't seem to do muchIs there an idle mixture screw somewhere? I've read also that som AFM have an adjusting screw. Is this the case with the 2tgeu?
I don't think I have the dizzy the wrong way round, because where you tighten the dizzy the screw sits in a closed channel and also limited by the fuel rail and block.
This engine was previously set up for twins, whould that have anything to do with it?
Thanks
David
Yes, and i just remembered i had it way out of wack when i was last running the efi gear.Originally Posted by Neverland
However, having said that, it should not be affecting you, i had it turned most of the way up ( you will not need to run it like this though, i had it turned up cause of my headgasket leek). So if anything it should be idling high...?
Are you talking about this engine?? If so, it can not be judged currently because the engine is clearly no opperating properally at the momentOriginally Posted by Neverland
. And when the engine is running properly, ie when i had it running, it had really good throttle response. So you can look forward to a responsive engine when you get it running properly
.
I hope ive helped a little, sorry bout my crappy electircal skills
